Today, at last, we now have both the chicken and the egg in the UK. For I’ve just driven the Toyota Mirai on a shiny new 65-plate, one of 30 or so Mirais that will be in the UK by the end of 2016. By that point there will be nine places in the UK you can fill it up, up from the three sites currently open.

Around 3000 Mirais will be produced in total by the end of 2017. The Mirai will be joined by, among other hydrogen cars, a new fuel-cell vehicle from Honda that’s due to be revealed at next week’s Tokyo motor show, plus likely efforts from Nissan, BMW and Mercedes-Benz, who are making more noises about the technology. Japan and Germany are getting serious about creating infrastructures, too.
